运行 neo4j DriverManager.getConnection 在 linux 时发出

Question

我正在尝试连接到 neo4j 远程服务器....如果我运行通过 windows 我的代码工作正常......但是当我将它作为运行nable jar 并尝试在我的 centos 中运行它抛出错误...

            String line="060100B075|MOC|20150407|16:28:23|81|0628001735";       
            String[] cols = line.split("\|");
            nodeCreation.createNodes(cols[0],cols[1],cols[2]);

//创建节点函数

            Connection con= DriverManager.getConnection("jdbc:neo4j://144.35.78.234:7474/");
            String Query = "MERGE (ABC:PLANE {name: " + "\""
                            + cols[0]+ "\"" + " }) RETURN ABC";
          try (PreparedStatement stmt = con.prepareStatement(Query)) {
            ResultSet RS = stmt.executeQuery();
        }

我能够从 window 连接并能够从 window..但不能从 linux 环境插入节点..我认为我的代码没有任何问题。 .我该如何解决..

这是我的 pom.xml 的样子：

尝试分享mvn dependency:tree, 可能是您的 hadoop 库引入了不同的版本。

另请了解准备语句中的参数并使用stmt.executeUpdate()

  Connection con=
    DriverManager.getConnection("jdbc:neo4j://144.35.78.234:7474/");
  String query = "MERGE (plane:Plane {name: {1}}) RETURN plane";
  try (PreparedStatement stmt = con.prepareStatement(query)) {
    stmt.setString(1,cols[0]);
    stmt.executeUpdate();
  }
